Van Alen Institute by collective-LOK in New York City

"the design team collective-LOK, comprised of new york and boston-based architects jon lott (PARA-project), william o’brien jr. (WOJR), and michael kubo (over,under), titles the ground floor space ‘screen-play’, for its use of different elastic partition elements. among these veil layers is a modular and porous coffer-like ceiling that diffuses lighting and acoustics while concealing projectors and mechanical equipment. additionally, a wall of accordion walls along with sliding translucent panels divide the open-program area from the private and semi-private spaces."
